Thus this curious apparatus not only furnishes oxygen, but also aids in locomotion. In the pupse of insects there is little or no motion, yet important organic changes are taking place —the worm-like, ignoble, creeping, often repulsive larva, is soon to appear as the airy, beautiful, active, almost ethereal imago. So oxygen, the most essential—the sine qua non—of all animal food, is still needed

The pupse no less than the larva? of some two-wing flies which live in water, have long tubes which reach far out for the vivifying air, and are thus called rat-tailed. Even the pupa of the mosquito, await- ing in its liquid home the glad time when it shall unfold its tiny wings and pipe its war-note, has a similar arrangement to secure the gaseous pabulum. The digestive apparatus of insects is very interesting, and, as in our own class of animals, varies very much in length and complexity, as the hosts of insects vary in their habits. As in mammals and birds, the length, with some striking excep-.
